我正在尝试使用 stripe_ payment 包在我的 flutter 应用程序中实现 Stripe 支付系统。在我的代码中，我调用 Stripe.instance.initPaymentSheet(...)，但是当我尝试在几行之后调用 Stripe.instance.presentPaymentSheet(...) 时，出现以下错误：
flutter: StripeException(error: LocalizedErrorMessage(code: FailureCode.Failed, localizedMessage: No payment sheet has been initialized yet, message: No payment sheet has been initialized yet, stripeErrorCode: null, declineCode: null, type: null))
这是我的代码：
Future<void> makePayment() async {
final url = Uri.parse(
'${firebaseFunction}');
final response =
await http.get(url, headers: {'Content-Type': 'application/json'});
this.paymentIntentData = json.decode(response.body);
await Stripe.instance.initPaymentSheet(
paymentSheetParameters: SetupPaymentSheetParameters(
paymentIntentClientSecret: paymentIntentData!['paymentIntent'],
applePay: true,
googlePay: true,

merchantCountryCode: 'UK',

setState(() {});
print('initialised');

我已经为我的 flutter 模块生成了“aar”文件，并将该 aar 文件包含在我的本机 android 应用程序中。现在，当我单击 Android 应用程序中的按钮时，我将通过 Android 中的 FlutterActivity 类启动我的 flutter 模块。
现在我的问题是，如何在本机 android 代码和生成的 aar 代码之间进一步通信？
如何编写我的 flutter 模块，以便当我生成“aar”文件并包含在我的 android 应用程序中时，我能够在它们之间建立通信？
